The pro-Israel special interest group is one of the most significant and pervasive special interest groups in the United States. It consists of numerous institutions and individuals that work to influence Congress, the president, academia, the media, religious institutions, and American public opinion on behalf of Israel. It has been active in the U.S. for many decades.

Below is a partial list, in no particular order, of groups and individuals that publicly support Israel.

Some of these are official lobbying groups whose primary purpose is to lobby governmental officials for pro-Israel policies. Others are groups or individuals that work to influence the media, academia and/or others in a pro-Israel direction. Some do this full-time; others as one portion of a diverse array of activities. While they span the political spectrum and range from hardcore supporters of the Israeli right to liberal critics of some Israeli policies, all support Israel.
